To understand the effects of oceanographic condition on the harvest of laver and establish the basic environmental data for cultivation farm of laver, a series of survey was carried out in Gojeong-ri sea area, west coast of Korea from January to September, 1987. Variation of water temperature in Gojeong-ri sea area was 3.8-25.8℃, pH was 7.8-8.4, and transparency was 1.3-3.1m. Salinity was changed from 19.57 to 31.99% and lower remarkably in July and August owing to a heavy rain. The concentration of DO in surface water wart varied from 9.4-10.1㎎/ℓ and in lower layer was 8.0-9.99㎎/ℓ . COD was 0-4.28㎎/ℓ by alkalic modification of potassium permanganate method. Distribution of total suspended solid was 13.7-488.7㎎/ℓ and the rate of light penetration in 1m water column was 7.2-15.5%. The concentration of nutrients were changed in 0.48-23.63㎍-at./ℓ for ammonia nitrogen, 0-4.45㎍-at./ℓ for nitrite nitrogen, 0.39-3.13㎍-at./ℓ for nitrate nitrogen, 0-21.42㎍-at./ℓ for phosphate, and 0.84-157.32㎍-at./ℓ for silicate. It was showed high concentration in summertime, raining season in general. The concentration of chlorophyll a was 0.39-20.62㎎/㎥. Total 57 species of phytoplankton and 21 groups of zooplankton were identified from collected samples. Dominant species were Coscinodiscus radiatus, Eucampia zodiacus as a phytoplankton and Noctiluca scinitillans, Cladocera, Copepods sp. as a zooplankton. The total standing crop of phytoplankton was ranged of 5,500-1,524,400cells/ℓ and that of zooplankton was 3,000-43,000 individuals/㎥.

This experiment was carried out in order to elucidate the effect of NaCl(0.85%) acclimation on congestion symptoms in central venous sinuses(CVS) of gill filaments and on the alteration of blood constituents in cultured eels for 1, 2, 3, 4, 5, 6 and 7days after handling stress. After giving a handling stress on eels, the frequency of gill congestion was about 90%. It gradually decreased to 40% on the 3rd day, then increased to 60% on the 7th day in NaCl(0.85%) acclimation. The values of haematocrit(Ht), methemoglobin(Met-Hb), glucose (GLU), calcium($Ca^{++}$), lactic dehydrogenase(LDH), glutamic pyruvic transaminase (GPT) and glutamic oxaloacetic transaminase(GOT) were lower than those of the control, whereas magnesium($Mg^{++}$) and haemoglobin(Hb) were higher than the control. However total protein(Tp) and albumin (ALB) levels similar to the control. When the fish after giving a handling stress were cultured in NaCl-free water as a control, the frequency of gill congestion and the value of blood components showed a similar pattern to that obtained from the NaCl acclimated experiments. However, in the early period(1-3day) after handling stress, NaCl acclimating slightly helped the natural tendancy of recovery. These results suggest that the frequency of gill congestion is not always reduced over the whole period of NaCl acclimation. However, the acclimation to NaCl solution may be a somewhat useful therapy for the gill congestion in stressed eels. 뱀장어에 인위적으로 스트레스를 가하여 아가미 울혈증을 발생시킨 후에 NaCl 처리에 따른 CVS의 울혈증의 치료효과 및 혈액성상의 변화에 미치는 영향을 조사하였다. 스트레스 직후에 고빈도의 발병율을 보였던 아가미 및 간의 울혈증은 염처리 후 3일째 까지는 감소되었으나, 4일 이후에는 별 영향이 없었다. 혈액성분중 스트레스 후 증가되었던 Ht, Met-Hb, $Ca^{++}$, GOT, GPT, LDH 및 glucose치 등과 감소되었던 $Mg^{++}$ 및 Hb치 등은 염처리 3일까지는 회복율이 촉진되었으나, 그 이후에는 큰 차이를 보이지 않았다. 그러나 알부민 및 총단백치는 염처리 기간동안 별 변화가 없었다. 이상의 결과는 스트레스에 의해 발병된 아가미 울혈증에 대한 염처리법은 초기 3일까지는 효과가 있으나, 그 이상의 기간에는 전혀 효과적이지 못함을 보여준다.

A 61-year old female presented with intermittent abdominal pain. Further examination showed an pelvic mass, partially obstructing the sigmoid colon. A search of the past medical records revealed that a primary low-grade ESS of the uterus had been treated with total abdominal hysterectomy and bilateral salpingo-oophorectomy 10 years earlier. Surgical resection was performed under suspicion of recurrent ESS and subsequent pathologic examination of the tumor mass specimen established the recurrent LGSS and free resection margin. Then she has been treated with megestrol acetate and doing well for about 1 year since the surgical resection of the pelvic mass.

Short-term acute toxicity of synthetic detergent(harmful and non-harmful detergents) to crusian carp, Carassius auratus was examined by static bioassay. The crusian carp was exposed to 10 different concentration of synthetic detergent for 240 hours in order to determine median lethal concentration(LC50). In case of harmful detergent, the 100% mortality was showed within 72 and 24 hours for 14 and above 20 ppm, but showed below 30% for until 10 ppm. For the non-harmful detergent, 80% of mortality was appeared for 450 ppm only The 48hr, 96hr and 240hr of median lethal concentration was found 12.85ppm, 11.86ppm !ind lO.36ppm respectively. The permissible toxicant concentration of acute toxicity to crusian carp was 1.19ppm. Gill tissue of dead crusian carp showed necrosis and blood vessel also damaged Epithelium of gill lamellae showed pronounced change in even 8 ppm below. During the test period, gills of survival animals appeared also change for non-harmful detergent. So, animals showed effection of detergent even though animals exposed to non-harmful detergent for long times.

Jeong, Gil-Sang,Kang, Tae-Hwa,Park, Hae-Chul,Choi, Ji-Young,Hwang, Seok-Jo,Kim, Won-Tae,Choi, Young-Cheol,Lee, Kyeong-Yong,Park, In-Gyun,Sim, Ha-Sik,Kim, Jong-Gill 한국응용곤충학회 2009 Journal of Asia-Pacific Entomology Vol. No.
Wolbachia is one of the most prevalent endosymbiontic bacteria of arthropods. The bacterium induces sex ratio distortions in various host insects through processes such as cytoplasmic incompatibility, feminization, male killing, and parthenogenesis, We investigated if the Korean endemic firefly, Luciola unmunsana was infected with the bacterium because the species had an abnormal sex ratio in the field. The results show that some individuals are infected with the bacterium. Phylogenetic analyses showed that the bacterial strain infecting the firefly is closely related to strains that infect phylogenetically distant hosts.

This study was conducted to investigate the distribution pattern, ecological characteristics and life cycle of the Black Soldier Fly (Hermetia illucens, BSF). The BSF was widely distributed throughout Korea. The insect was mainly found in the vicinity of and in cattle sheds, manure sheds, living waste dump grounds, and food waste dump grounds. Developmental characteristics of the BSF are as follows: the egg was long oval shaped of 887㎛ in the major axis and 190㎛ in the minor axis; it weighed 24㎍. Female oviposited ca. 1,000 eggs on average; eggs hatched in 81 hours under laboratory condition (27℃, 60% R.H.). The duration of the larval stage was approximately 15-20 days. The size of the last instar larvae was 21mm. The cuticle of the pupae gradually acquired red-brown color and the size of them was 19 mm. The pupal stage was shorter for females (16 days) than males (15 days). Adults were sized about 13-20mm long and black-colored. The life span of adult insects was 5-8 days for the first generation (June-July), 7-10 days for the second generation (Aug.-Sept.), and 13-18 days for the third generation (Sept.-Oct.). Mating started on the next day of emergence and actively occurred at the third day after emergence. Mating mostly occurred between 10:00 and 16:00 during which light intensity is highest. Egg-laying started on the third day and was most frequent from the fourth to the sixth day after emergence. Similar to mating time, females oviposited mostly between 10:00 and 16:00.
